Letters Patent No. 109,822, detea December e, 1870.

IMPROVEMENT IN FEED-CUTTERS.

The Schedule referred to in these Letters Patent. and making part of the same.

To whom, 'it may concern:

Be it known that I, WILnrAM HU'roHnvs, of Paw Paw, in the county of Van Buren andv State of Michigan, have invented a new and useful Improvement in a F eed-Cutter; and I do declare that the following is a true and accurate description thereof, reference being had to the'accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure l is a perspective view of my device.

Figure 2 is a cross-.section through the cutting-box taken on the line x ein fig. l.

Figure 3 is an enlarged side elevation of the cuttingbox,detached, to show the operation of the self-adjusting Weighted feed-roll.

Like letters indicate like parts in each figure.

'The nature of this invention relates to adevice for' cutting hay, straw, stalks, &c., into feed of any desired ineuess for feeding to stock.

' The invention consists in the peculiar construct-ion and arrangement of a Vself-adjusting weighted toothed,y

upper feed-roll, in combination with a corrugated lower feed-roll and other devices, as more fully hereinaftery Set forth. f

In the drawingv A represents aproper frame, across the middle part of which is journaled the shaft B, whichv may be rotated by hand or power. A

'On this shaft is keyed a ily-wheel, C, on opposite spokes or arms of which are secured Vtwo curved knives, D, by proper set-screws.

Preferably I make these knives ln the form of a segment of a circle, so that as they revolve past'thev throat of the cutting-box E they will sever Vthe projecting fodder with a shearing or drawing cut.

F is a shaft journaled iu the' frame at right angles with the shaft B, from which it receives motion through the bevel-wheels c b, keyed to the respect-ive shafts.

\G is a shaft journaled in the frame parallel with Vthe shaft F, but passing through the lower part of the throat of the cutting-box,pwhere it carries a feedroll, G.

On theoverhangiug end of the roll-shaft G is secured a differential or coued gear-wheel, H, having three or more spur-gears of 'various diameters, with 011e of which a pinion, I1", meshes, and rotates the roll-shaft.

Corresponding pinions are kept on a suitable stud ready for use, when the speed of the roll-shaft requires to be changed.

The feed-roll G is serrated 6r corrugated in the direction of itslength to'compel the material to feed.

YI are plates sliding in ways at the sides of the cutting-box directly over the lower feed-roll.

lu these plates is journaled a toothed feed-roll, J.

To .the platesI is suspended a stirrup, K, which serves asa fulcrum tothe weighted lever L, pivoted under the cutting-box.

By adjusting the weight c. ou the lever any desired/ l manner:

A'pair of standards, M, are erected on the main fra-me directly over the shaft G, and in them is journaled a short shaft, N, carrying a pinion, O, meshing with a spur-wheel, l, ofthe same diameter keyed to the feed-shaft G below. g

A-tumbling-rod,Q, provided with a universal joint, d, at 'each end, couples the shaft N with that of the upper feed-roll, so that the latter may be free to move up or down while in motion.

In cutting various kinds of feed the change-wheels 4F may be used of the size which will increase or diminish the speed of the feed-rolls with relationto the number of' revolutions of the knife-wheel, so that the fodder willbe cut to the desired length.

In feeding through the cutting-box the different kinds of'fodder, the right pressure of the upperv feedroll, to insure their passage, is obtained by adjusting the weight onv the lever L.

Iam aware that there are feed-cutters whose specific parts are constructedsubstautiallylike mine, and also feed-'cutters `having a combination of parts substantially similar to those found iu 'portions of my device, and do not claim to have invented such, but only the particular combination hereinafter set forth as my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the toothed upper feed-roll J, tumblingrod Q, with universal jointd d, sliding plates I, stirrups Ii, lever L, and weight G, with the lower corrugated feed-roll G', all constructed and operating substantially as described and shown, for the purposes set forth.
